1 Under what conditions can a stalemate occur in Heroes 5?
About Standard
If a specific game time is given (e.g., 1 game month), and the players haven't managed to play to victory. And no clear advantage has been identified.
About Duels
Possibly, at the discretion of the tournament organizer - the annihilation of all creatures in both armies with Armageddon.
If you mean a battle between heroes in standard mode, then yes :D it's a flaw.
:smile02: You're right, unlike in Heroes 3, the hero can also attack, so the tactic of a fast warrior running away from a slow one won't work. (the hero will catch up :))
The rules should be updated.
